This cultivar is named for its stunning clusters of deep, cherry-red, double-petal flowers. The double blooms give them a fuller, more impactful look than traditional single-petaled varieties. They appear profusely from early summer into the fall, providing a long season of intense color. The leaves are a glossy, dark green throughout the growing season. In the fall, the foliage turns attractive shades of orange and red, adding a final burst of color before the leaves drop.
